On the occasion of the 80th anniversary of the suffering of Zrin, a monograph entitled ”Zrin – in memory of the victims of genocide” by Damir Borovčak, a patriotic activist, political analyst, organizer, travel writer, publicist and historical researcher, was presented to the public. This large-format, high-quality work on almost 400 pages aims to tear the horrific Partisan crimes against the innocent population of ancient Zrin from oblivion. This book was published on the occasion of the 80th anniversary. On the feast of the Assumption of the Blessed Virgin Mary, on September 9 and 10, 1943, the Partisans and Chetniks killed almost a third of the inhabitants in a genocidal campaign, burned the parish church of the Finding of the Holy Cross, as well as the entire village. All survivors were displaced by the communist authorities, confiscated their property and prohibited from returning to Zrin. In addition to historical facts and numerous documents and photographs, the book also brings invaluable written testimonies, confessions of the survivors of Zrin and the actors of those terrible events.
